Continuous Commissioning

What is continuous comissioning and monitoring?

Buildings do not work as intended and miss their initial performance targets in operation. In fact the gap between design values and operational consumption is estimated to be as large as 30%.

Continuous commissioning is the process of identifying design targets and continuously monitoring the achievement of these targets to identify performance drift and maintain better control of your buildings.

Define Targets

Set and define optimal design values for operational performance data, such as Room CO2 and temperature, supply air from an AHU and Chiller COP etc.

Measure & Evaluate

Every 15 minutes, 24 hours a day, 365 days a year automated KPIs are produced to allow you to measure your buildings key metrics, compare against design values and ensure high performance is being achieved.


When performance drift occurs, provide clear and understandable actions to improve performance and return systems back to their baseline targets.

Do buildings truly underperform ?

Yes, it is well documented and understood that buildings rarely meet their design intent and the performance drifts over time. In fact the REHVA Quality Management Guidebook, 2019 outlines that the gap between design values and operational energy consumption to be as large as 30%.

Our data collectors and sensor technology are built and designed to be as seemless as possible to install. Once the right requirements are available from the Building Management System (BACNet/Modbus and it is configured correctly) then we can have you up and running with ongoing data capture in a matter of days. From there we just need to work with you to understand and identify the design targets for each system in order to start benchmarking against.

We retain all data both raw values and generated KPIs on our platform for up to 3 years at a granularity of 15 minutes. If you require access to longer timeframes of data we can discuss options to doing so.

The benefits of continuous commissioning all revolve around the fact that you will achieve better control of your building and systems. Some benefits include: Reduced time of getting new buildings operational. Reduced overall energy consumption. Improved performance transparency and maintenance transparency. Better comfort and air quality for occupants. Our case study library contains concrete examples of all of this in action.
